Summer meteor showers are underway. When to see Perseids, more in Missouri
Following nearly a two-month "shooting stars" drought, three meteor showers are set to become active concurrently in July. The celestial activity will then hit a crescendo in August with the peak of what is widely considered the best meteor shower of the year: the Perseids.
With its whizzing meteors and blazing fireballs, the Perseid meteor shower reliably puts on a spectacle every year for stargazers around the world. Spectators who step outside at just the right time could be treated to up to 100 Perseid meteors per hour streaking across the night sky, leaving long wakes of light and color behind them.
But what's the best part of the Perseids? Because they peak in summer, spectators don't have to contend with cold weather like they do when other famous meteor showers such as the Leonids and Geminids hit their peak activity.
Here's everything Missouri stargazers should know about the summer's meteor showers, headlined by the spectacular Perseids.
When, where to see the Perseid meteor shower in 2025
In 2025, the Perseid meteor shower is expected to become active Thursday, July 17, and remain so until Aug. 23, according to the American Meteor Society.
The Perseids are best viewed in the Northern Hemisphere.
Once the sun sets and the moon is below the horizon, spectators should only have to contend with local light pollution and clouds that could interfere with the number of meteors they can see.
Like all meteor showers, the Perseids are best viewed during the dark hours between midnight and dawn. However, it is possible under the right conditions to view Perseid meteors as early as 9 p.m. Central time, according to NASA.
These 2 meteor showers are set to peak at same time
What's more, the Perseids aren't the only meteor shower lighting up the night sky this summer.
Both the Southern delta Aquarids and the alpha Capricornids are due to peak at the same time between July 29 and July 30, according to the American Meteor Society.
The Capricornids began their activity July 12 and will be followed by the Southern delta Aquarids (also spelled "Aquariids") Friday, July 18. Both meteor showers will remain active until Aug. 12.
Unfortunately, neither shower is famed for being very strong.
The Southern Delta Aquarids are faint meteors that are difficult enough to spot as it is. But if the moon is visible at all, it will be near impossible, according to NASA.
Perseid meteor shower 2025: When activity peaks
This year, the Perseids are expected to peak the night of Aug. 12-13.
Though the Geminids in December are considered to be one of the strongest and most consistent meteor showers, the Perseids still result in anywhere from 50 to 100 meteors visible per hour under the right conditions.
What's more, the Perseid meteor shower gained its reputation for the plentiful whizzing meteors and blazing fireballs it reliably produces each year pretty much around the globe. These large explosions of light and color can persist even longer than an average meteor streak, NASA says.
Could the moon interfere with Perseids? Tips for seeing meteor shower
Unfortunately, the Perseid meteor shower is peaking three days after a full moon in 2025. For that reason, a bright waning gibbous moon could outshine the fainter of the streaking meteors and make them more difficult to spot.
But for those determined to catch a few of them, NASA has these viewing tips to increase your odds:
Find an area distant from city light pollution or street lights.
Bring a sleeping bag, blanket, or lawn chair. Lie flat on your back and look up, taking in as much of the sky as possible.
After about 30 minutes in the dark, your eyes will adapt and you will begin to see meteors.
The website TimeandDate also provides detailed information about where and when to see the phenomenon.
What causes the Perseid meteor shower?
Originating from the constellation Perseus, the Perseids are made up of leftover particles from comet 109P/Swift-Tuttle.
Every year, Earth passes through the comet's debris trail, resulting in the Perseid meteor shower when the broken bits of Swift-Tuttle disintegrates in our atmosphere at high speed – creating fiery and colorful streaks in the sky known colloquially as "shooting stars," according to NASA.
Swift-Tuttle, which takes 133 Earth years just to orbit the sun a single time, was discovered to be the source of the Perseids in 1865 by Italian astronomer Giovanni Schiaparelli. Discovered in 1862, Swift-Tuttle is absolutely gargantuan – twice the size of the asteroid theorized to have wiped out the dinosaurs 66 million years ago.

Researchers Discovered Two Basic Habits That Can Prevent Alzheimer's, And My Aging Millennial Brain Is Paying Attention
Can delaying a disease as monstrous as Alzheimer's be as simple as walking and eating nutritious foods? To some degree, yes. A June 2025 study in Molecular Neurodegeneration assessed this topic and concluded that 'up to 45% of dementia risk can be attributed to modifiable risk factors,' namely exercise and diet. What happens, the study explained, is that those two habits boost BDNF, or brain-derived neurotrophic factor. BDNF is a protein that aids neuroplasticity, or the brain's ability to adapt, learn and remember. HuffPost spoke to a doctor about the study's findings, and he said they make sense. Related: 'Walking and diet are two of the simplest ways we know to boost BDNF, a key protein that helps brain cells grow, repair and communicate,' said Dr. Alexander Zubkov, a neurologist and board advisory member of 1MD Nutrition who specializes in neurodegenerative disorders and functional medicine. 'Higher BDNF levels are strongly linked to better memory and slower cognitive decline.' The opposite holds, too: A decrease in BDNF is often seen in people who have neurological conditions such as Alzheimer's, according to a 2015 study in Archives of Medical Science. But what does 'delaying Alzheimer's' even mean in this case? And how much walking and which foods are most helpful? Ahead, we'll answer those questions and more with insights from the study and Zubkov. What does 'delaying Alzheimer's' even mean? Related: Is 'delaying Alzheimer's' the same as preventing dementia diseases completely, or can it only be applied to people who are currently or about to develop the condition? 'When we talk about 'delaying Alzheimer's,' we're not talking about preventing the disease entirely,' Zubkov said. 'We're talking about slowing how quickly the symptoms appear or progress.' For someone who's starting to experience early changes in their brain, he continued, that could mean a few extra years of clear thinking and independence. That's significant. How does walking generate BDNF? Related: As mentioned, walking is a crucial way to increase BDNF expression. A 2025 study in Brain Sciences reported that walking, particularly at moderate to high intensities, increases BDNF levels, especially right after the exercise. It also found that walking increased BDNF by 11%. But how does that happen? 'Something as basic as a brisk daily walk increases blood flow and oxygen to the brain, which naturally stimulates BDNF release,' Zubkov explained. How much should you walk a day to delay Alzheimer's? Zubkov said there's no 'one magic number' of steps, but he's seen research consistently assert a certain range. 'Most data points to about 7,000 to 8,000 steps a day as a realistic sweet spot for brain and heart health,' he said. That's roughly three to four miles, or an hour to a little over an hour, of walking. The pace matters, too. He encouraged aiming for a brisk pace — aka, fast enough that you can talk, but not sing — for maximum benefits. Additionally, the study found positive results with both acute and long-term exercise. So, try to keep your exercise consistent, but don't give up if you skip a few days. Every walking session counts. What foods can help delay Alzheimer's disease? Related: Nutrition is another key piece, though perhaps not as key as walking. According to the original study mentioned, researchers need more and consistent information on the most beneficial dietary factors and how different foods affect different biomarkers (the latter includes certain proteins, blood pressure and tumors, for example). Additionally, it's important to note that most current research looks at a combination of factors, not diet alone. 'Pairing [walking] with nutrient-rich foods … gives the brain the building blocks it needs to stay resilient,' Zubkov said. With that said, knowledge about brain-healthy foods does exist. The study found positive results with the MIND-diet, or the Mediterranean-DASH Intervention for Neurodegenerative Delay. It's a hybrid of the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) antihypertensive diet. The MIND-diet includes whole grains; dark, leafy, green vegetables; nuts; olive oil; berries; and even red wine, among other foods and beverages. Zubkov recommended a few key nutrients: omega-3s, antioxidants and polyphenols. More specifically, he encouraged people to eat fatty fish, walnuts, leafy greens and berries, and to drink green tea. Are there other ways to generate BDNF? The other tips Zubkov shared are the typical self-care recommendations you've heard from your doctor: aerobic exercise, resistance training, quality sleep, and stress reduction. Here's a glimpse into what each of those can look like: Aerobic exercise: dancing, swimming, the elliptical, cycling, running Resistance training: push-ups, squats, lunges, planks, using free weights Quality sleep: around six to eight hours, and not 'junk sleep,' aka too little or not solid sleep Stress reduction: deep breathing, talking to friends, meditation, listening to music He added that some early research is looking at peptides, or building blocks of proteins, such as Semax, Selank, and Dihexa, when it comes to influencing BDNF. But beware: 'These are still experimental and should only be used under medical supervision,' Zubkov clarified. Let's keep it simple: If you want to delay Alzheimer's onset, focus on walking and adding nutritious foods, such as walnuts, whole grains and dark green vegetables, into your diet. As both studies and doctors will tell you, these daily habits have a significant impact on your article originally appeared on HuffPost. Also in Goodful: Also in Goodful: Also in Goodful:

Even Low Lead Exposure Can Impair Academic Outcomes in Kids
TOPLINE: Every 1-unit increase in blood lead levels in early childhood — even when below the 'safe' threshold of 3.5 µg/dL — was associated with declines in math and reading scores from grades 2 through 11, similar to those seen at higher lead levels. METHODOLOGY: Researchers used the 2021 US CDC's revision of the blood lead reference value to ≥ 3.5 μg/dL. They analyzed data from birth certificates of children born in Iowa from 1989 to 2010, academic test scores from grades 2 through 11, and blood lead testing data from 1990 to 2017. The analysis included 305,256 children (mean age at lead testing, 1.9 years; 49% girls) and nearly 1.8 million math and reading scores to calculate the national percentile rank (NPR). Primary outcomes included NPR scores across grades 2 through 11, comparing children with blood lead levels < 3.5 μg/dL with those at or above this threshold. TAKEAWAY: Overall, 37.7% of children had lead levels < 3.5 μg/dL. Among children with blood lead levels < 3.5 μg/dL, a 1-unit increase was associated with lower NPR scores in math (-0.47; 95% CI, -0.65 to -0.30) and in reading (-0.38; 95% CI, -0.56 to -0.20). Similarly, for lead levels at ≥ 3.5 μg/dL, every 1-unit increase was linked to a significant decline in NPR scores for math and reading. The trend of declining scores with increasing lead levels was persistent across grades 2 through 11; only the declines in reading scores for grades 10 and 11 were not statistically significant. IN PRACTICE: 'The present work provides further evidence to support that there are no safe levels of lead and that there is a need to continue to reduce or eliminate lead exposure,' the authors of the study wrote. SOURCE: This study was led by George L. Wehby, MPH, PhD, of the Department of Health Management and Policy at the University of Iowa in Iowa City, Iowa. It was published online on May 28, 2025, in JAMA Network Open. LIMITATIONS: Several laboratories used the old 5 μg/dL cutoff to quantify high lead levels. Researchers lacked data on any lead-related interventions the children may have received. DISCLOSURES: Wehby reported receiving grants from the Gates Foundation during the conduct of this study. This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

NASA announces retirement of veteran astronaut Butch Wilmore after 25 years of service
NASA has announced the retirement of test pilot and astronaut Butch Wilmore after 25 successful years of service and flights aboard four different spacecraft. Wilmore, a veteran pilot and graduate of the U.S. Naval Test Pilot School, has logged 464 days in space since his selection by NASA in 2000. The decorated U.S. Navy Capt. has flown on the Space Shuttle Atlantis in 2009, Roscosmos Soyuz in 2014, Boeing Starliner in 2024, and returned to Earth aboard SpaceX Dragon most recently. He also completed five spacewalks for a total of 32 hours outside the International Space Station. "Butch's commitment to NASA's mission and dedication to human space exploration is truly exemplary," said Steve Koerner, acting director of NASA's Johnson Space Center in Houston. "His lasting legacy of fortitude will continue to impact and inspire the Johnson workforce, future explorers, and the nation for generations. On behalf of NASA's Johnson Space Center, we thank Butch for his service." Wilmore has been recognized as not only technically gifted but also an adaptable astronaut whose legacy spans decades of advancing human spaceflight across many missions. He was one of the few astronauts that flew aboard both NASA's legacy and commercial vehicles which helped validate critical systems for long-term human spaceflight. "Throughout his career, Butch has exemplified the technical excellence of what is required of an astronaut. His mastery of complex systems, coupled with his adaptability and steadfast commitment to NASA's mission, has inspired us all," said Joe Acaba, chief of the Astronaut Office at NASA Johnson. "As he steps into this new chapter, that same dedication will no doubt continue to show in whatever he decides to do next." Wilmore's most recent launch aboard Boeing's Starliner spacecraft on June 5, 2024, marked the first crewed flight test mission. During the mission, they were able to help remove a radio frequency group antenna assembly and collect samples for analysis from the Destiny laboratory and the Quest airlock. "From my earliest days, I have been captivated by the marvels of creation, looking upward with an insatiable curiosity. This curiosity propelled me into the skies, and eventually to space, where the magnificence of the cosmos mirrored the glory of its creator in ways words can scarcely convey," said Wilmore. "Even as I ventured beyond Earth's limits, I remained attuned to the beauty and significance of the world below, recognizing the same intricate design evident among the stars is also woven into the fabric of life at home." Wilmore's retirement signals the end of NASA's pioneering era of cross-platform astronaut missions and early commercial spaceflight validation.
